SPECIFICATION forming part of Letters Patent No. 452,906, dated May 26,1891.

Application tiled July 8, 1890. Serial No. 358,092. (No model.)

To all whom it nmy concern.'

BeitknownthatLWILLIAMTHoMAsLocks, a citizen of the United States,residing at Springdale, in the county of Washington and `ment, and.combination of parts which will be hereinafter fully described, andpointed out in the claim.

- In the drawings, Figure 'l is a perspective view of a corn-planterembodying my improvements. Fig. 2 is a longitudinal vertical sectionalview of the same. Fig. 3 is a vertical transverse sectional view. Fig. 4is a perspective detail view of the beam and seedslide detached.

Like numerals of reference indicate like parts in all the gures.

The frame of my improved corn-planter is composed of side pieces 1 1,spaced at their rear ends by a cross-piece 2.

3 designates the tongue, the rear end of which is made of a width equalto the length of the cross-piece 2. The wide rear end of the tongue islitted between the front ends of the side beams 1 1, where it is heldsecurely by means of screws or bolts. The rear end of the widened end ofthe tongue is provided with a notch or recess 4, in which is mounted theseed-slide 5, which has a longitudinallyreciprocating movement in saidnotch or recess. The seed-slide is provided with a perforation orseed-cup 6, which, when the said slide is at the forward limit of itsmovement, is in alignment with an opening 7 in the widened portion ofplate 8 at the rear end of the tongue. A flat spring 9, secured to theupper side ofthe tongue and bent into an inverted-U shape, bears againstthe front edge of the seed-slide and serves to force the latter normallyin a rearward direction.

The under sides of the side beams 1 1 are provided with bearings for theaxle 10, carry-s in gV the drive and bearing wheel 11, which is providedin one side with a cam-shaped projection 12.

13 designates an upright mounted upon one of the side beams 1, and tothe upper end of said upright is pivoted a lever 14, which extendsdownwardly in rear of an arm or lug 15, that extends rearwardly from theseed-slide. The lower end of the lever 14 hangs in the path of thecam-shaped projection 12 of the driving-wheel. When the latter revolves,the said projection will engage the lever 14, which in turn bearsagainst the projection 15 at the rear end of the seed-slide, forcing thelatter in a forward direction against the tension of the spring 9. Thelatter, as soon as the projection 12 passes the lever 14, serves torestore the seed-slide to its normal position.

1G designates the hopper, which is provided at its lower edge with aflange 17 to receive screws or bolts, by means of which it is secured tothe upper sides of the side beams 1, thus retaining in position theseed-slide 5. The front portion of the flange 17 has a notch 1S for thepassage of the spring 9.

19 designates the handles, which are secured to the side beams l, andwhich are connected in the usual manner by a cross-piece or round 20. Toone of said handles is pivoted a catch or turn-button 21, which, whendesired, may be used to support the lever 14 in a raised position out ofthe path of the projection 12 of the drive-wheel.

22 designates the furrow-opener, which is composed, mainly, of a narrowsharp-edged shank provided at its upper edge with lianges 23 and 23, bywhich it is secured to the under side of the tongue. The rear liange 23is provided with a recess 24 in its upper side to receive the upper endof a curved standard 24, which is secured in position by the same boltwhich passes through the flange 23% The lower end of the standardcarries a plow 25, the point of which rests in a notch 28 in the rearedge of the furrow-opener to prevent said plow-point from catching inweeds or trash.

By the construction above described the curved standard carrying theplow serves to brace and strengthen the furrow-opener, and the latter,which serves to cut a furrow in front of the plow, serves to guard thepoint of the latter.

Covering-plows 2G are secured to the under sides of the side beams at asuitable distance in rear of the furrow-opener.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of my invention willbereadily understood by those skilled in the art to which it appertains.

Whenthe machine progresses over the field, the projection l2 of thedrive-wheel every time it comes in contact with the lever 14 will serveto force the seed-slide in a forward direction against the tension ofthe spring, thus causing a portion of the contents of the hopper to bedropped through the opening 7 and into the furrow prepared for itsreception. The spring 9 serves to restore the seedslide automatically toits normal position. The covering-plows 2G serve to cover the seed inthe usual manner, and the drive-wheel, which will have a tread of anydesired width, serves to compact the soil over the seed. It is obviousthat the distance between the hills may be varied by using more than oneprojcction 12 upon the side of the drive-wheel 25 and properlyregulating the distance between such projections.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- The combination of the frame, thefurrowopener having iianges 23 and 23, the latter provided with arecess24 in its upper side, the curved standard 24, carrying the plow 25, anda recess 2S to accommodate the point of the latter in the rear side,near the lower end of the furrow-opener, the upper end of said standardbeing seated in the recess 24:a and secured by the bolt which securesthe flange 23a to the under side of the tongue, as set forth.

In testimony that I claim the foregoing as myown I have hereto afliXedmy signature in presence of two witnesses.
